403 permission errors for specific, sensitive Google services (Gemini, Google Console) from Iran.

The occurrence of 403 permission errors for services like Gemini and Google Console, particularly from Iran, indicates that the domain-fronting relay is failing to effectively mask the origin or is being detected as a proxy. These services often employ sophisticated IP-based access controls and fraud detection. A 403 error suggests the request is understood but explicitly denied, implying the service recognizes the connection as originating from a restricted region or via an unauthorized method. This directly undermines the product's core value proposition of bypassing DPI and accessing restricted content, especially for users in highly censored environments. The market demands a solution that can reliably circumvent such advanced detection.
